Re: Problems porting from old Compilation Manager

Documentation for the 110.0.7 version of CM can be found at

	http://smlnj.org/doc/CM/Old/index.html

the new version is documented at

	http://smlnj.org/doc/CM/new.pdf

The main difference is that the newer version of CM requires explicit
mention of the basis ($/basis.cm) in CM files and the role of groups
changed (which may not be an issue).

The other porting problems will have to do with the SML'97 Basis
specification, which 110.0.7 predated.  The Basis library is documented
at

	http://www.standardml.org/Basis/

Please let us know if you have any questions.
